Supply AU when an editor, player, or delivery form will not accept WAV
Create a AU copy from WAV for Unix workstations and older audio software

Local conversion competes with other open apps for processor time during this WAV-to-AU job.
Large WAV inputs may take several minutes on older hardware.
Inspect the AU file in the exact player or editor that will receive it.

AU serves Unix workstations and older audio software, whereas WAV commonly serves DAWs, editors, podcasts, and production delivery.
For WAV-to-AU delivery, plan for limited modern consumer support.
After leaving WAV, the receiving app must support the streams encoded inside AU, not only its extension.

WAV to AU taking too long? Check available memory; long, high-resolution sources need substantially more.
AU converted from WAV not opening? Test a compatible player and inspect the output streams.
Check whether the receiver supports this AU variant: limited modern consumer support.

When does WAV to AU conversion make sense?

It is useful when WAV media created for editing and interchange must enter a AU system designed for legacy workstation exchange.

Where is the WAV source processed?

The browser prepares AU from WAV on this device instead of sending the source to a remote conversion server.

How can I approve AU converted from WAV?

Test the AU file in the receiving app and compare duration, channels and loudness with the WAV source.
